I came to this conclusion by comparing the information in the article along with its one picture, and the other links. I don't currently have any further information, but I have to wonder if the article helped?

At Eldonejo Mistera Sturno I publish free ebooks of Jack Vance translations, each with a mini dictionary to help komencantoj. Recently I combined six, interlinked stand-alone stories into one six-part book so as to match the original, classic edition: The Dying Earth.

Since each former stand-alone had its own dictionary and I wanted for the combined book to have a single larger one...to interleave them would have meant hundreds of cut-and-paste operations. Rather than do it by hand, I wrote a Perl script instead.
